Application filed- February 18- L906. -Sarial1iw800.849- I To all whom it meyconcer'n:

"Be it known that I,'JOH'N W. Kane's, -a=citilinville in the count of Cattaraugusnand State of New-Yorkplia new andousetul improvements in .Gas=..or other Explosive Engines, :ofi which the following is aspecification.

The present invention relates to improvements 111 was or other. explosive engines, and particular y to the mechanism for admitting the exploded charge from the explosion chamber to the'engine to be driven.

lnsmany gas: engines as now constructed and-operated, .it has been found very difficult to operate the valve, which closes the explosion chamberiwihile charging, at the proper instant to get the greatestpower'from the .explosion to the engine, for various reasons, one of which is that. amechanically actuated valveottenfails to open to its extreme position-.with. sufficient rapidity to pass thecharge to. the en ine.

The objects 0 the improved construction shown herein. are to provide, in an explosive engine, a valve which may be positively closed andso. held,:b .an 'electroemagnet, and novisionis made or an electric circuit inclu ing a contact surface onpoint on a moving element of the engine, whereby thevalve may be held in closed position when the circuit IS UIOSGLl, and the circuit broken almost; simultaneouslywith the explosion in .the chamber thus releasin -the valve-and permitting. the passsa e of t e exploded charge-to theengine.

to compress a charge of gas and air in the explosion chamber, and the charge is exploded as usual.

It will be understood that the valve which constitutes the armature for the magnet, and the explosion chamber are constructed of magnetic metal; and the material of which the expansion chamber is constructed, is of non-magnetic metal.

It will be understood that I do not limit myself to the hinged or swinging form of valve shown, nor to the precise location of chamber and the engine.

the valve, it being only necessary that the valve be disposed between the explosion A reciprocating engine might be used, and diilerent kinds of valves employed, such for instance as a. plug valve, adapted to fit, when closed, in a complementary-seat.

()mreference to Figs. 4 and 5, it will be seen that the pinion 27 of the main shaft, and the gear 28 on a short shaft, will operate to energize or denergize the magnet, say once in every three revolutions of the main shaft, thus demagnetizing the valve so that an explosion may occur once in three revolutions of the shaft of the engine; or the gear 28" may be used instead of the gear 22, and

' thus the moving contact disk or rib be located on the pinion for driving the compressor. This construction will produce an explosion at the end of every charging stroke of the compressor.

Larger or smaller gears may be substituted for the gears 27 and 28, contact piece 29 being employed on each of the lower pinions, and the stat onary contact piece 30 may be moved at Wlll to positions required by the size of the pinion used on the lower shaft.

may be held in closed position, by the mag netic energy, until the charge in the explosion chamber reaches its predetermined.

maximum pressure preparatory to the explosion thereof, and the valve, or armature of the magnet, be de-magnetized at varying mtervals, but with accuracy and reliability.

Many other modifications, changes, and alterations mayl be made in the practical applicatlon of t e principles of the invention, wlthm the scope of my claims, without departin from the spirit thereof, as the draw mgs il ustrate only several examples of the physical embodiment of the invention, and I contemplate changes and alterations in the practical use of the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In an engine the combination, of an explosion chamber, a hinged valve located between said chamber and the engine piston, a coil surrounding the walls of said chamber and said walls forming the core of a magnet, and electrical connections to said coil whereby the valve is held in closed position.

2. In an engine the combination with an explosion chamber, of a valve located between said chamber and the engine piston, a coil surrounding the walls of the explosion chamber and said walls forming the core of a magnet whereby when the magnet is energized the valve is held closed; a stationary contact point, and a moving contact point on the engine, in electrical circuit, for releasing said valve.

3. The combination with an explosion chamber having a shoulder formed at lts end, of a swinging valve adapted to bear against said shoulder and close thechamber, and an electro-magnetic coil surrounding the walls of said chamber adapted when energized to hold the valve closed, and said walls forming the core of a magnet; and means for denergizing the magnet to permit the valve to be opened at the time of explosion.

4. The combination in an ex losive engine, of an expansion chamber an an ex losion chamber and a hinged valve located t erebetween, a coil surrounding the walls of the explosion chamber and said walls forming the core of a magnet, and electrical connections for energizing the magnet to hold the valve closed and denergzing the magnet to permit the valve to open.

5. In an engine the combination of an ex plosion chamber and an expansion chamber and a valve hinged therebetween, a valve seat formed at one end of the explosion chamber, a coil surrounding the walls of the explosion chamber and adapted when energized to hold the valve against its seat, the walls of the explosion chamber forming the core of a magnet and an electrical circuit including said coilhaving means therein for intermittently magnetizing and demagnetizing the valve to close and 0 en the same.

n testimony whereof I a ix my signature in presence of two witnesses.
